process hung problem + self reset

[aratti]

Very likely the problem is the time taken to dtmfout between the two serin command. If the for/next loop takes just longer than allowed you miss tx bytes and your system is out of syncronism. (Remember you have a wait comand)

Remove

dtmfout porta.3 ,100 ,100,[ 10 , 0 , 10 ]
             
             
     for x = 0 to 20
                   pause 10
                 if  gdata[x] = "." then
                    gdata[x] = 12
                    endif
                      dtmfout porta.3 ,100,100,[ gdata[x]  ]  
                       
  next x

And dtmfout after the second serin command, to be sure to avoid loosing tx bytes

my serial data source is repeat it self continuously
when the first package arrive the the buffer will be load
and then first (FOR) loop will execute meen while there is serail data looses

after first (FOR LOOP)

the second serial in command will wait for other Sync WORD "SD"
because serial source repeat all data packages continuously (if because of loop
i miss the first appearing of "SD" at the end i'll catch it no matter what )

it works gooood

all data transmit ok and tone appear OK for 9 to 10 min of operation and the two FOR LOOP update continuously

--------------------------------------------------------
the hung is apear on tone sound

normaly DTMFOUT sounds apear like this

[toot -- teet -- tut -- tat -- tet - toot --tiit - toot ----> for 10 minuets ]

and then it become sounds like this after 10 min

[teeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeet] -------> till reset
